Description
Technical field
The present invention relates to the device of plate progressive molding technical field.Specifically be a kind of sheet metal deep drawing and progressive compound molding device of being used for.
Background technology
The plate progressive molding is the sheet forming technology of rising in recent years, has that forming mode is flexible, forming property good and characteristics such as flexible height, is specially adapted to the production and processing of the sheet metal product of single-piece and small lot.Progressive molding is to adopt " track " manufacturing process; Carry out the generation of surface profile through the motion of tool heads; Therefore curring time is high more a lot of than drawing and forming, and because the flowing and the stress state more complicated of plate when being shaped, the dimensional accuracy of the back part that is shaped also is difficult to constraint and controls.People such as G.Hirt had once proposed to adopt first pull and stretch to carry out preform in " Investigation into anewhybrid forming process:Incremental sheet forming combined with stretch forming " (CIRP Annals-Manufacturing Technology); Adopt the method for progressive molding process details characteristic then, proved that precision and curring time all have improvement with respect to simple progressive molding.But; This method is lived blank holder and stationary table with bolt; Limit flowing of plate, adopt servomotor to control downward stroke downwards in the drawing process, following shortcoming is arranged in forming process like this: 1) owing to adopt bolt control to flow; Therefore the metal of flanging part does not almost inwardly flow in the process that stretches, and causes the shaped region attenuate serious; 2) tensile force that is provided of servomotor is limited, can not satisfy the shaping of the higher plate of intensity, promptly bigger drawing pressure can not be provided, and working environment requires high.
Summary of the invention
The object of the invention is exactly for the defective that overcomes above-mentioned prior art existence a kind of flowing of metal blank of controlling to be provided, and effectively reduces the reduction of plate, improves the progressive compound molding device of sheet metal deep drawing and the manufacturing process thereof of the forming accuracy of plate.
The object of the invention can be realized through following technical scheme: the progressive compound molding device of a kind of sheet metal deep drawing; It is characterized in that; Comprise: numerical control progressive molding lathe, tool heads, base plate, hoist cylinder, lead, platen, oil pressure corner oil cylinder, blank holder, mould seat, half module, wherein: described hoist cylinder is installed on the base plate and with platen and is connected, and described lead is installed on equally on the base plate and with platen and is connected; Described oil pressure corner oil cylinder is installed on the platen; Described blank holder places on the platen and through oil pressure corner oil cylinder and fixes, and described half module is installed on the mould seat, and the mould seat is fixed on the base plate; Base plate is installed on the workbench of numerical control progressive molding lathe, and described tool heads is installed on the main shaft end of numerical control progressive molding lathe.
Described tool heads is the various milling cutters that can select as required or the different diameters and the contour squeeze of terminal sample, but tool heads is through the main shaft rotation of driven by motor winding number control progressive molding lathe.
Described hoist cylinder adopts the double-cylinder hydraulic structure, realizes being synchronized with the movement of two hydraulic cylinders through the servo balance valve.
Described lead comprises guide pillar and guide pin bushing, and guide pillar is fixed in base plate, and guide pin bushing is fixed in platen, when bedplate up-down, play the guiding role.
A kind of plate adopts the progressive combined shaping method of pull and stretch of said apparatus; It is characterized in that; This method may further comprise the steps: at first plate is placed between blank holder and the platen; Oil pressure corner oil cylinder is pushed down blank holder, and the size of pressure-pad-force makes it when pull and stretch, to provide suitable pressure-pad-force in the adjustment corner oil cylinder; Then, hoist cylinder drives platen, blank holder and plate and moves downward, and plate is fixed in mould seat and base plate in descending process half module pushes, and begins to take shape required form; After drawing and forming was accomplished, numerical control progressive molding lathe drove tool heads and by the product design shape plate local feature is carried out progressive molding, accomplished to be shaped; After progressive molding is accomplished, the tool heads milling cutter that changes the outfit, numerical control progressive molding lathe drives milling cutter and along product edge the required part of plate is downcut, and obtains product.
Compared with prior art, the present invention overcome plate thickness skewness in traditional progressive molding, the serious problem of local reduction, and forming efficiency is higher than traditional progressive molding through regulating the pressure-pad-force in the drawing and forming; With respect to process of sheet forming, the present invention institute only needs simple simple and easy half module to be shaped, and is lower to the be pilot cost; In addition, drawing and forming, progressive molding and side cut process slitless connection do not need travelling workpiece and relevant again to work such as coordinates, can increase work efficiency in a nearly step.
